d3c608aaec jesd204sync: reset and check lock status of DDMTD helper PLL in firmware 2019-01-31 15:11:16 +08:00
c591009220 sayma: report TSC phase of SYSREF (TSC LSBs on SYSREF rising edge) in SYSREF sampler
Better visibility, better diagnostics, allows some changing of SYSREF frequency while keeping the same gateware.

cb04230f86 sayma: SYSREF setup/hold validation demonstration
This also removes the standalone target as the ISERDES used
for setup/hold check requires the fine RTIO clock, which in turn
requires a DRTIO transceiver due to the Ultrascale TPWS bug.

4941fb3300 sayma: 2.4GHz DAC clocking (4X interpolation)
* gets another clock divider out of the way
* gets one cycle within range of the HMC7043 analog delay alone
* SYSREF/RTIO alignment removed, to be replaced with DDMTD-based scheme

49f7a1610f sayma: use GTP_CLK1 only for all variants (#1080) 2018-08-07 20:53:14 +08:00
f87da95e57 jesd204: use jesd clock domain for sysref sampler
RTIO domain is still in reset during calibration.

76fc63bbf7 jesd204: use separate controls for reset and input buffer disable 2018-06-22 11:38:18 +08:00
d9955fee76 jesd204: make sure IOB FF is used to sample SYSREF at FPGA 2018-06-22 11:00:56 +08:00
de7d64d482 sayma: clock JESD204 from GTP CLK2
This frees up GTP CLK1, which is routable to the SFP quads, for DRTIO.
